GRANDVIEW, MO (KCTV) -

The unlikely rescuers who helped a Kansas family of seven trapped on their roof have departed to Houston in hopes of helping others impacted by flooding.

Their heavy expanded mobility tactical truck (HEMTT) was used last week to rescue Kansas City residents left stranded on their roof in floodwaters.

The truck gets four miles to the gallon, weighs 40,000 pounds and is on its way to help Harvey victims in Houston, and the two guys who own the HEMTT are no strangers to rescuing flood victims.

Spencer Sherf and Cyrus Dawson left just before 9 p.m. on Monday. They have friends and family in the Houston area who are safe. They hope to help strangers still in harm's way.

They're loading up supplies Monday night, including a jet ski, a life raft and life jackets.

After hearing from friends in South Texas, the pair knew they needed to go help.

"They asked me what base I was from and where I was coming from and didn't realize we were just private citizens. And I actually sent one of the guys a picture, and they said 'Bring that thing right now,'" Sherf said.

Dawson and Sherf say they are coordinating with the Houston Police Department.

Emergency responders sent Dawson a list of things they need the most like diapers, over the counter medical supplies, diabetes test strips, dog and cat food and water.

They want to load up the truck and take as many supplies down as they can.

A Facebook post from a local teacher that said the Florida shooting had her so on edge she was actually considering ending her 35-year career in education had us wondering how many other teachers are having that kind of internal crisis.
